Safety Information (Continued)
Cold Weather Operation of Powershift P.T.O.s
WARNING: During extreme cold weather operation [32°F (0°C) and lower], a
disengaged Powershift Power Take-Off can momentarily transmit high torque that will
cause unexpected output shaft rotation. This is caused by the high viscosity of the
transmission oil when it is extremely cold. As slippage occurs between the Power Take-Off
clutch plates, the oil will rapidly heat up and the viscous drag will quickly decrease.
The Power Take-Off output shaft rotation could cause unexpected movement of the driven
equipment resulting in serious personal injury, death, or equipment damage.
To avoid personal injury or equipment damage:
■
Driven equipment must have separate controls.
■
The driven equipment must be left in the disengaged position when not in operation.
■
Do not operate the driven equipment until the vehicle is allowed to warm up.
Rotating Auxiliary Driveshafts
WARNING:
■
Rotating auxiliary driveshafts are dangerous. You can snag clothes, skin, hair, hands,
etc. This can cause serious injury or death.
■
Do not go under the vehicle when the engine is running.
■
Do not work on or near an exposed shaft when the engine is running.
■
Shut off the engine before working on the Power Take-Off or driven equipment.
■
Exposed rotating driveshafts must be guarded.
Guarding Auxiliary Driveshafts
WARNING: We strongly recommend that a Power Take-Off and a directly mounted
pump be used to eliminate the auxiliary driveshaft whenever possible. If an auxiliary driveshaft is used and remains exposed after installation, it is the responsibility of the vehicle
designer and P.T.O. installer to install a guard.
This symbol warns of possible personal injury.

Safety Information (Continued)
Using Set Screws
WARNING: Auxiliary driveshafts may be installed with either recessed or protruding
set screws. If you choose a square head set screw, you should be aware that it will
protrude above the hub of the yoke and may be a point where clothes, skin, hair, hands,
etc. could be snagged. A socket head set screw, which may not protrude above the hub of
the yoke, does not permit the same amount of torquing as does a square head set screw.
Also, a square head set screw, if used with a lock wire, will prevent loosening of the screw
caused by vibration. Regardless of the choice made with respect to a set screw, an
exposed rotating auxiliary driveshaft must be guarded.
IMPORTANT: Safety Information and Owner’s Manual
Chelsea Power Take-Offs are packaged with safety information decals, instructions, and an
owner’s manual. These items are located in the envelope with the P.T.O. mounting gaskets.
Also, safety information and installation instructions are packaged with some individual
parts and kits. Be sure to read the owner’s manual before installing or operating the
P. T. O. Always install the safety information decals according to the instructions provided.
Place the owner’s manual in the vehicle glove compartment.
WARNING: Operating the P.T.O. with the Vehicle in Motion
Some Power Take-Offs may be operated when the vehicle is in motion. To do so, the P.T.O.
must have been properly selected to operate at highway speeds and correctly matched to
the vehicle transmission and the requirements of the driven equipment.
If in doubt about the P.T.O.s specifications and capabilities, avoid operating the P.T.O. when
the vehicle is in motion. Improper application and/or operation can cause serious personal
injury or premature failure of the vehicle, the driven equipment, and/or the P.T.O.
Always remember to disengage the P.T.O. when the driven equipment is not in operation.
Pump Installation Precautions (see next page)
Use a bracket to support the pump to the transmission if:
■ The pump weighs 40 pounds [18.14 kg] or more.
■ The combined length of the P.T.O. and pump is 18 inches [45.72 cm] or more from the
P.T.O. centerline to the end of the pump.

Foreword
Since it is our major objective to show you how to get additional and more profitable
miles from truck, tractor, and trailer components, we want to provide you with information
on the installation of Chelsea Power Take-Offs.
We all realize that an inadequate Split Shaft will overwork any Power Take-Off in a very
short period of time. In addition, a mismatched Split Shaft/P.T.O. combination can result
in unsatisfactory performance of the equipment right from the start.
Before you order new trucks, be sure that you’re getting the right Gear Box, Split Shaft or
P.T.O. combination. This is vital for efficient performance and adequate power. To help you
select the proper type, size, and design of P.T.O., discuss your specific requirements with
a Chelsea P.T.O. specialist. They know their products and have easy access to equipment, transmission, and Power Take-Off manufacturers. They can tell you everything you
need to know about power, at the right time, before you specify components.
Chelsea P.T.O. Safety Label Instructions
1. The two black and orange on white 5" x 7" pressure sensitive vinyl labels, part number
379274; must be placed on the vehicle frame rails (one (1) on each side), in a position
that would be HIGHLY visible to anyone that would go under the truck near the P.T.O.
rotating shaft. If the vehicle is to be painted after these labels are installed, cover them
with two-(2) blank masking covers. Remove the masking covers after painting.
2. Place the one (1) black and orange on white 3.5" x 5" pressure sensitive vinyl label, part
number 379275, on the visor nearest the operator of the vehicle, this must be placed
near the P.T.O. visor label.
3. Place the one (1) red and white with black lettering 3.5" x 7.5" sensitive vinyl label, part
number 379915, on the opposite side of the visor from the above label # 379275.
4. Place the one (1) white and black heavy duty card, part number 379276, in the vehicle
glove box. Again in a position highly visible to the operator, for example: try to place this
card on top of whatever may be in the glove box.
If you require additional labels, please order part number 328946X at no charge from your

Installation of a Split Shaft
Application Data for Installation of a Split Shaft
Split Shaft Through Torque Ratings
The torque capacity of the Chelsea Split Shaft units is limited by either the engine capacity
or the vehicle wheel skid conditions. To correctly choose a split shaft model for a given
application, the maximum torque from the engine, and the maximum torque due to wheel
conditions, should be calculated. The limiting value obtained by these calculations should
then be compared with the charted split shaft torque capacity.
Formula
Maximum Through Torque From the Engine
1.
Maximum Torque From the Engine = Maximum Net Engine Torque X Manual Transmission Low Gear Ratio X 85% Efficiency
2.
For an automatic transmission, the maximum torque from the engine should be taken
from the engine-transmission performance curve stall torque valve. This information is
generally available from the manufacturer of the automatic transmission.
Maximum Torque Due to Wheel Skid Conditions
3.
Maximum ft. lbs. of Torque = GVW x f x RAD
12 x AR
Where:
GVW

Based on past experience, the coefficients of friction used have been:

= 0.8 for on-highway service (dry pavement)
= 0.5 for off-highway service
These are generally used values but if information is available for a specific application,
the appropriate coefficient of friction can be used.

Installation of a Split Shaft
Lubrication Information
To insure proper lubrication and operating temperatures in these units, it is most important
that the proper lubricants be used and that correct oil levels be maintained.
Recommended Lubricants
The following lubricants are recommended, in order of preference, for use in all Chelsea
Split Shafts and Gear Boxes.

MIL-L-2104B or MIL-L-45199 Series 3
Straight Mineral Gear Oil
Do Not Use Extreme Pressure Additives, such as found in multi-purpose or rear axle
type lubricants. These additives are not required in our split shafts and gear boxes, and
they may in some cases create transmission problems. Multi-purpose oils, as a group,
have relatively poor oxidation stability, a high rate of sludge formation and a greater
tendency to react on or corrode the steel and bronze parts.
Oil Changes
We recommend an initial oil change and flush after the split shaft is placed in actual service.
This change should be made any time following 1,000 miles, but never to exceed 4,000
miles, of over-the-road service. In off-highway use, the change should be made after 24 and
before 100 hours of service have elapsed. There are many factors that influence the
following oil change periods, and we have not specified a definite mileage interval.
In general, it is suggested that a drain and flush period be scheduled every 20,000 miles for
normal over-the-highway operations. Off-the-highway usually requires an oil change every
30 days. The oil level in the split shaft should be checked every 2,000 miles on-highway, or
every 24 hours in off-highway operation. When it is necessary to add oil, we recommend
that types or brands of oil not be mixed. The correct oil level in all Chelsea Split Shafts is
established by the filler plug opening.
Refill—First, remove all dirt around the filler plug. Then refill with new oil of a grade recommended for the existing season and prevailing service.
Overfilling
Do not overfill the gear box or split shaft. Overfilling usually results in oil breakdown due to
excessive heat and aeration from the churning action of the gears. Early breakdown of the
oil will result in heavy varnish and sludge deposits that plug up oil ports and buildup on
splines and bearings. Overflow of oil usually escapes onto clutch or parking brakes,
causing additional trouble.

Installation of a Split Shaft
Owner’s Manual
Split Shafts and Gear Box
Installation Instructions—Split Shaft
Split shaft Power Take-Offs are installed into the vehicle driveline. This requires cutting and
reworking driveshafts. No attempt will be made here to list driveline fabrication or rework procedures. For answers to specific questions, contact the Drivetrain Service Division. Listed are
the necessities for a good Power Take-Off installation that will run quietly and without
vibration. The unit itself should be suspended from a rubber isolated crossmember and will
replace the center bearing for the driveline. Grade 8 bolts should be used for all fastenings.
1.
Front—a short coupled joint connecting the transmission to the split shaft should be
installed so as to permit equal joint angles of less than 3°.
Rear—A two joint assembly connecting the split shaft to the rear axle should be
installed so as to permit equal joint angles of less than 5° to insure the best
performance. The joint angles should be kept within a minimum of 1° to 3°.
Front & Rear—the two joint assembly at the front and rear should be installed so as to
permit equal joint angles of less than 5°.
2.
Determine a suitable location for crossmembers for mounting the split shaft. Raise or
lower or move the split shaft front or rear as required to reduce the joint angles to a
minimum but not less than 1°.
3.
Align the split shaft with the transmission and rear axle.
A. For the best installation and optimum performance, the input and output shafts of
the split shaft should be parallel respectively within 1° to the main shaft of the
transmission and the pinion shaft of the axle.
B. With the shafts parallel, the joint angles should be in one plane only. Make sure the
offset in the horizontal or vertical planes will provide for equal joint angles of less
than 3° with a short coupled joint or less than 5° with a two joint assembly.
4.
Excessive angles result in a loss of speed and power. The figures shown below are
approximate and any angle less than those shown will provide a better installation.

Slight angles of 1° in each joint are necessary for the circulation of the needles.
5.
The front and rear shafts should be assembled, straightened, and balanced before
installation.

When filling the 912 series split shaft unit with oil it is always important not to over fill the
Power Take-Off unit. This is very important when installing two 885 series P.T.O.s.
A change was made to the 912 housing (1-P-484) lowering the fill plug located on the lower
right rear of the housing (see drawing, Note A). To verify that you have a 912 housing that
has the proper plug location for checking the oil level with two 885 Power Take-Offs, check
for the “Revision” level of the housing. This revision level is in the form of a letter located on
the driveline output side of the housing and located to the right of the casting number (see
drawing, Note B). If the Revision letter is “J” or higher then the plug in the housing has
been changed for the correct oil level for two 885 series Power Take-Off.
On all other applications or with one 885 series P.T.O. use the oil level plug located on the
left side of the housing to check for proper oil levels (see drawing, Note C).

Installation of a Gear Box
Owner’s Manual
Split Shafts and Gear Box
Installation Instructions – Gear Boxes Models 700, 712, 721, 732,741,
2230, and 2442
Gear boxes are installed very similarly to split shaft Power Take-Offs. The differences are
that the gear box is driven from a Power Take-Off rather than the transmission main shaft,
and the gear box drives a piece of equipment rather than the rear axle. Installation of a
gear box requires fabrication of new shafts rather than cutting into the existing driveline.
Listed are the necessities for a good gear box installation which are basically the same as
those required for a good split shaft Power Take-Off installation. The unit itself is mounted
on a plate which must be mounted to a sturdy support on the vehicle. Rubber isolation of
the unit is important to prevent transmitting vibrations throughout the vehicle. Then follow
the steps below:
1.
Front—The short coupled joint connecting the Power Take-Off to the gear box should
be installed so as to permit equal joint angles of less than 3°.
Rear—The two joint assembly connecting the gear box to the driven equipment should
be installed so as to permit equal joint angles of less than 5°. To insure the best
performance, the joint angles should be kept within a minimum of 1° to 3°.
Front & Rear—The two joint assemblies at the front and rear should be installed so as
to permit equal joint angles of less than 5°.
2.
Determine a suitable location for mounting the gear box. Raise or lower or move the
gear box front or rear as required to reduce the joint angles to a minimum, but not less
than 1°.
3.
Align the gear box with the Power Take-Off and driven equipment.
A. For the best installation and optimum performance, the input and output shafts of
the gear box should be parallel respectively with 1° to the output shaft of the Power
Take-Off and the input shaft of the driven equipment.
B. With the shafts parallel, the joint angles should be in one plane only. Make sure the
offset in the horizontal or vertical planes will provide for equal joint angles of less
than 3° with a short coupled joint or less than 5° with a two joint assembly.
4.
Excessive angles result in a loss of speed and power. The figures shown below are
approximate and any angles less than those shown will provide a better installation.
Speed
5,000 R.P.M.
4,000 R.P.M.
3,000 R.P.M.
True Joint Operating Angle
3° 15'
4° 15'
5° 50'
Slight angles of 1° in each joint are necessary to permit circulation of the needles.
5.
If at all possible, the shafts front and rear should be assembled, straightened, and
balanced. The various models of gear boxes offer three (or several) types of shifters.
Wire shift is installed identically to a six bolt Power Take-Off installation. Linkage for
lever controls must be designed and fabricated by the installer. Air shift plumbing is
shown in the typical sketch on pages 33-35 for a single acting air shift.

Installation–P.T.O. to a Split Shaft
Application Questions for Installation of a P.T.O. to a Split Shaft
Specifying and mounting a P.T.O. to the 912
& 914 Split Shaft is accomplished the same
as on a transmission. There are certain
application questions and installation
procedures that you should follow. The next
four pages will take you through these steps.
1.
What is the make and model of your
transmission?
2.
Which P.T.O. opening will be used?
3.
What accessory is to be driven?
4.
How much horsepower is required to
drive the accessory?
5.
What is the required rotation of the
P. T. O. ?
6.
What is the required P.T.O. output shaft
speed as a percent of engine speed?
7.
S.A.E. 6 Bolt
S.A.E. 8 Bolt
What is the required method of shifting Standard SAE Power Take-Off Apertures
the P.T.O. – cable, lever or air?
Once all the answers to these questions
have been determined, a transmission
mounted P.T.O. can be selected to meet the
horsepower, speed, and rotation that you
require.

1.
Drain the oil from the transmission, and
remove the P.T.O. aperture cover plate.
(See Fig. 1.)
Fig. 1
2.
Discard the cover plate and cover plate
gasket. Clean the aperture pad using a
putty knife or wire brush. (See Fig. 2.)
NOTE: Stuff a rag in the aperture
opening to prevent dirt from entering the
transmission while you are cleaning it.
3.
Using your hand, rock the P.T.O. drive
gear in the transmission (See Fig. 3.) and
the driven gear in the P.T.O. assembly
(See Fig. 4.). Rocking the gears provides
two important factors.
Fig. 2
A. It shows you the amount of backlash
that has been designed into each unit.
B. It is helpful in establishing the proper

4.
Install the proper studs in the P.T.O. aperture pad using a stud driver. (See Fig. 5.)
5.
Where holes are tapped through the
transmission case, use Permatex or an
equivalent to prevent leaks.

6.
Tighten the studs securely, and torque
them to 10 - 15 ft. lbs. (1.38 - 2.07 kg.
meters) for the 6 bolt and 15 - 20 ft. lbs.
(2.07 - 2.77 kg. meters) for the 8 bolt.
(See Fig. 6.)
7.
Place the correct number of gaskets
over the studs. (See Fig. 7.) Do not use
Permatex between gaskets because you
may want to add or subtract gaskets to
obtain the proper backlash.
Fig. 6
• When mounting a P.T.O., use gaskets
between all mounting surfaces.
• Do not stack more than 3 gaskets
together.
• Usually one thick gasket .020"
(.50 mm) will be required.
• Remember the lubricant in the
transmission also lubricates the P.T.O.
Therefore, at least one gasket must
always be used on either side of filler
blocks, adapter assemblies, or
adapter plates. More gaskets may be
required when establishing proper
backlash.

Cable Control Installation Instructions*
1.
Find a suitable area on the dash to install the cable control (328346-10X) and the
control plate (68-P-18) indicator light.
Optional Location: As an option the control cable and knob can be located through floor.
Using this option the control plate and indicator light should still be located on dash, in
close proximity.
NOTE: The location of the cable control and the control plate should be as close to
each other as possible and easily accessible by the driver or operator, but should not be
an obstacle to driver movement nor interfere with other controls, instruments, or
equipment.
2.
CAUTION: Before drilling any holes, make sure there is adequate room on both sides
through dash wall, drill a 1/2" (.5") diameter hole for the control cable. [1]
3.
Install the control cable on the dash using the hex nuts supplied with the cable. The
knob can then be screwed into place [2]. The length of cable can then run through the
firewall and back to the P.T.O. —making sure it is kept away from the exhaust, moving
parts, etc.
NOTE: Do not kink the cable. In order for the cable to operate properly, there can be
no bends smaller than 6 inch radius. Total bends in the cable should not exceed 360°
(example - four 90° bends in cable).
4.
Using the template found on page 38
(SK-168) drill the necessary holes for the
control plate-indicator light.
5.
Install the control plate (68-P-18) stick on
decal and indicator light on the dash using
the hardware supplied in the 328751-1X
installation kit (Fig. 25).

Cable Control Installation Instructions (Continued)
6.
Determine from which direction the cable must come in order for the unit to be
disengaged when the knob is all the way in.
NOTE: The shifter must always be installed in the following manner:
* CABLE IN: P.T.O. DISENGAGED(6A): OUT OF GEAR POSITION
CABLE OUT: P.T.O. ENGAGED(6B): IN GEAR POSITION
* The wire shift cable should be installed so that when the cable (knob) is pushed all
the way in, the P.T.O. has also moved the full travel of the P.T.O. shifter, to the
disengaged mode.
7.
Install the wire control bracket found in either the 328380X or 328380-1X wire control
parts bag. [7]
8.
Line the cable up with the wire control bracket and shifter lever (disengaged position)
on the P.T.O. cover assembly [8]
NOTE: It may be necessary to change the position of the shifter lever on the P.T.O. To
do this, remove the shifter cover from the unit. This will prevent the possible loss of the
poppet and/or spring into the transmission if the shifter post assembly should be
pushed through the cover when reinstalling the lever.
9.
Shift the P.T.O. to the engaged position to see how much of the cable casing must be
cut to allow the lever enough travel to shift in and out completely. The casing need only
go just beyond the bracket, whereas, the wire must be long enough to go through the
swivel pin in the shifter lever. [9]
NOTE: In some instances the cable control may not be long enough. Chelsea has
available four longer lengths than the standard ten-foot cable. These come in five foot
increments (i.e., 328346-15X = 15-foot cable).
10. When the length of the casing has been determined, pull the wire back through until the
case can be cut without cutting the wire. Use a hacksaw or heavy pair of side cutters to
cut the casing.
NOTE: The cable can be held by a bench vise as long as the jaws are not tightened to
the point where the case mushrooms. If a vise is not accessible, a pair of vise grips will
do the job.

Continuity Check
Continuity Check
379639 and 379652 Indicator Switches
In order to insure that the switch is
functioning properly, the following procedure
can be used with the unit on a bench, or
installed.
1. Use a continuity checker, battery type,
either meter or light. Attach one (1) probe
to the screw on the 379639 or 379652
Indicator Switch.
Note: Make sure 379639 and 379652
Indicator Switches in the P.T.O. shifter or
housing are torqued to 10-15 ft. lbs.
(1.38-2.07 kg meters).
Fig. 23
2. With the other probe, make contact with
the shifter cover or housing (Fig. 23).
3. Actuate shifting device and the meter or
light* should be actuated when P.T.O.
gear is engaged (Fig. 24).
4. Shift unit out of gear and the meter or
light* should return to normal as shown.
Fig. 24
This test procedure can be used to check
Chelsea wire, lever, and air shifter covers,
although an air source would be necessary
for the latter.
* If a meter is not available the light in the
328751-1X can be used. A six volt battery is
all that is necessary for a power source.
CAUTION: Indicator switches are capable of 0.5 amps maximum.

Troubleshooting

Split Shafts and Gear Box
Troubleshooting
Driver Training: One of the major causes of bearing and gear failures in the auxiliary unit
is poor driving habits. Drivers should be taught to always use the Lo Speed or reductions
available in the auxiliary unit and keep the front box in the higher ratios not vice versa.
Worn and pitted gears, as well as worn and pitted bearings are usually caused by excessive
use of the auxiliary overdrive gears with the mainbox in lower gear ratios.
Broken teeth in the auxiliary unit are usually caused by drivers trying to start their vehicles
with the auxiliary unit in the high ratio while the big reduction is made in the front box.
Frogging or quick release of clutch gives a jump start which is also noted for breaking teeth.
Noisy Operation: Noise is usually very elusive and generally not the fault of the auxiliary;
therefore, mechanics should road test to determine if the driver’s complaint of noise is
actually in the auxiliary. Remember that auxiliary units act as sounding boxes and in
numerous instances, drivers have insisted that the noise was in the auxiliary. However,
investigations revealed the noise to be caused by one of the following conditions:
A.
B.
C.
D.
E.
F.
G.
H.
I.
J.
K.
L.
M.
N.
O.
P.
Fan out of balance or bent blades.
Defective vibration dampers.
Crankshafts out of balance.
Flywheels out of balance.
Flywheels mounting bolts loose.
Engine rough at idle producing rattle in gear train.
Clutch assembly out of balance.
Engine mounts loose or broken.
P.T.O. gear not fully engaged or housing not properly shimmed.
Universal joints wornout.
Propeller shafts out of balance.
Universal joint angles out of plane or at an excessive angle.
Center bearings in driveline dry, not mounted properly, etc.
Wheels out of balance.
Tire treads humming or vibrating at certain speeds.
Air leaks on suction side of induction system—especially with turbo-chargers.
Mechanics should try to locate and eliminate noise by means other than auxiliary removal,
or overhaul. However, if the noise appears to be in the auxiliary, try to break it down into the
following classifications. If possible, determine what position the gear shift lever is in when
the noise occurs. If the noise is evident in only one gear position, the cause of the noise is
generally traceable to the gears in operation.
A.
Growling and humming or, more serious, a grinding noise. These noises are
caused by worn, chipped, rough, or cracked gears. As gears continue to wear, the
grinding noise will be noticeable, particularly in the gear position that throws the
greatest load on the worn gear.

Troubleshooting
B.
Hissing or, more serious, a thumping or bumping type noise. Hissing noises can
be caused by bad bearings. As bearings wear and retainers start to break up, etc.,
the noise could change to a thumping or bumping.
C.
Metallic rattles within the auxiliary usually result from a variety of conditions.
Engine torsional vibrations are transmitted to the transmission through the clutch,
which may be amplified and transmitted to the auxiliary through the connecting
propeller shaft. In heavy duty equipment, clutch discs with vibration dampers are
not used, so a rattle, particularly in neutral, is common with diesel equipment. In
general, engine speeds should be 600 R.P.M. or above to eliminate objectionable
rattles and vibration during the idle. Always leave the main box in neutral and the
auxiliary unit in gear when idling. A defective or faulty injector would cause a
rough or lower idle speed and a rattle in the auxiliary. Rattle could also be caused
by excessive backlash in P.T.O. unit mounting.
D.
Improper lubricants or lack of lubricant can produce noises. Auxiliaries with low
oil levels sometimes run hotter than normal, as there is insufficient lubricant to
cool and cover the gears.
E.
Squealing, particularly when the auxiliary is operating at higher speeds, could be
caused by one of the free running gears seizing on the thrust face or fluted
diameter temporarily and then letting go. In general, a mild seizure will clear itself
up and the auxiliary will continue to operate satisfactorily without this defect being
known. See “G.”
F.
Gear seizure at High Speed, usually accompanied with a loud squealing noise,
is readily apparent to the driver, since the truck will suddenly slow down as if the
brakes were being applied. If the truck continues to move ahead, even though
the gear shift lever is placed in neutral, it would indicate the floating gear on the
main shaft had seized. Depressing the clutch should interrupt the driving torque.
The seized gear could be checked quite readily by depressing the clutch and
checking the action with the gear shift lever progressively in all shift positions. If
releasing the clutch tends to kill the engine, then this gear position has not
seized. In other words, the auxiliary would be in two gears at the same time. By a
process of elimination, the gear at fault can be readily identified. See “G.”
G.
Vibration. Gear seizures on thrust faces or fluted diameters are usually caused
by vibrations in the power train. This could be engine, propeller shafts, joint
angles, rear axles, differentials, etc.

Power Take-Off Maintenance
Owner’s Manual
Split Shafts and Gear Box
Power Take-Off Maintenance
Due to the normal and sometime severe torsional vibrations that Power Take-Off units
experience, operators should follow a set maintenance schedule for inspections. Failure to
service loose bolts or Power Take Off leaks could result in potential auxiliary Power Take-Off
or transmission damage.
Periodic P.T.O. MAINTENANCE is required by the owner/operator to ensure proper, safe and
trouble free operation.
Daily:
Check all air, hydraulic and working mechanisms before operating
P.T.O. Perform maintenance as required.
Monthly:
Inspect for possible leaks and tighten all air, hydraulic and
mounting hardware, if necessary. Torque all bolts, nuts, etc.
to Chelsea specifications. Insure that splines are properly
lubricated, if applicable. Perform maintenance as required.
With regards to the direct mounted pump splines, the P.T.O. requires the application of a
specially formulated anti-fretting, high pressure, high temperature grease. The addition of
the grease has been proven to reduce the effects of the torsional vibrations, which result in
fretting corrosion on the P.T.O. internal splines as well as the pump external splines. Fretting
corrosion appears as a “rusting and wearing” of the pump shaft splines. Severe duty
applications, which require long P.T.O. running times and high torque may require more
frequent regreasing. Applications such as Utility Trucks that run continuously and are lightly
loaded also require frequent regreasing due to the sheer hours of running time. It is
important to note that service intervals will vary for each and every application and is the
responsibility of the end user of the product. Chelsea also recommends that you consult
your pump owners manuals and technical services for their maintenance guidelines.
Fretting corrosion is caused by many factors and without proper maintenance; the anti-fretting
grease can only reduce its effects on components.
Chelsea offers the grease to our customers in two packages. The first is a 5/8 fluid ounce
tube (379688), which is included with every applicable P.T.O., and the second is a 14-ounce
grease cartridge (379831). Chelsea also offers greaseable shafts for most all output
designators.
Warranty:
Failure to comply entirely with the provisions set forth in the appropriate
Owner’s Manual will result in voiding of ALL Warranty consideration.
